It is a real R4 DS, but not made from the original R4 teams, as they stop producing the product. Basicaly, it's like you buy stuff from Zavvi now instead from Virgin Mega Store.

It's not fake, mean cheap, easy to break product. I had mine for a few months and its lovely. Never give me any trouble. And I am sure that it won't PHYSICALLY break your DS, there is no modification to DS OS, all the software you need will be put on the Micro SD card.

I tell you what, if you are willing to pay £3 extra, I will buy 1 GB Micro SD and put the software on for you, and I will show you how to get the games and how to put onto the memory card. SO everything you need is setup and ready to go.
